OKHttpUtil

在Java的世界中，Http客戶端之前一直是Apache家的HttpClient占據(jù)主導(dǎo)，但是由于此包較為龐大，API又比較難用，因此并不使用很多場(chǎng)景。而新興的OkHttp、Jodd-http固然好用，但是面對(duì)一些場(chǎng)景時(shí)，學(xué)習(xí)成本還是有一些的。

很多時(shí)候，我們想追求輕量級(jí)的Http客戶端，并且追求簡(jiǎn)單易用。而OKHttp是一套處理 HTTP 網(wǎng)絡(luò)請(qǐng)求的依賴庫(kù)，由 Square 公司設(shè)計(jì)研發(fā)并開(kāi)源，目前可以在 Java 和 Kotlin 中使用。

對(duì)于 Android App來(lái)說(shuō)，OkHttp 現(xiàn)在幾乎已經(jīng)占據(jù)了所有的網(wǎng)絡(luò)請(qǐng)求操作，對(duì)于服務(wù)器端請(qǐng)求外部接口也是必備的選擇 。針對(duì)OKHttp，OkHttpUtil做了一層封裝，使Http請(qǐng)求變得無(wú)比簡(jiǎn)單。

OKHttpUtil 功能

• 根據(jù)URL自動(dòng)判斷是請(qǐng)求HTTP還是HTTPS，不需要單獨(dú)寫(xiě)多余的代碼。

• 默認(rèn)情況下Cookie自動(dòng)記錄，比如可以實(shí)現(xiàn)模擬登錄，即第一次訪問(wèn)登錄URL后后續(xù)請(qǐng)求就是登錄狀態(tài)。

• 自動(dòng)識(shí)別304跳轉(zhuǎn)并二次請(qǐng)求

• 支持代理配置

• 支持referer配置

• 支持User-Agent配置

• 自動(dòng)識(shí)別并解壓Gzip格式返回內(nèi)容

• 支持springboot 配置文件

• 極簡(jiǎn)的封裝調(diào)用

OKHttpUtil使用

maven引入

<dependency><groupId>io.github.admin4j</groupId><artifactId>http</artifactId><version>0.4.0</version> </dependency>

最新版查詢：

https://search.maven.org/artifact/io.github.admin4j/http

GET

最簡(jiǎn)單的使用莫過(guò)于用HttpUtil工具類快速請(qǐng)求某個(gè)接口：

Response?response?=?HttpUtil.get("https://github.com/search",?Pair.of("q",?"okhttp")); System.out.println("response?=?"?+?response);

POST

一行代碼即可搞定，當(dāng)然Post請(qǐng)求也很簡(jiǎn)單：

#?JSON?格式的body Response?post?=?HttpUtil.post("https://oapi.dingtalk.com/robot/send?access_token=27f5954ab60ea8b2e431ae9101b1289c138e85aa6eb6e3940c35ee13ff8b6335",?"{\"msgtype\":?\"text\",\"text\":?{\"content\":\"【反饋提醒】我就是我,?是不一樣的煙火\"}}"); System.out.println("post?=?"?+?post);#?form?請(qǐng)求 Map<String,?Object>?formParams?=?new?HashMap<>(16); formParams.put("username",?"admin"); formParams.put("password",?"admin123"); Response?response?=?HttpUtil.postForm("http://192.168.1.13:9100/auth/login",formParams ); System.out.println("response?=?"?+?response);

返回格式為JSON的 可以使用 HttpJsonUtil 自動(dòng)返回JsonObject

JSONObject?object=HttpJsonUtil.get("https://github.com/search", Pair.of("q","http"), Pair.of("username","agonie201218")); System.out.println("object?=?"+object);

文件上傳

File?file=new?File("C:\\Users\\andanyang\\Downloads\\Sql.txt"); Map<String,?Object>?formParams=new?HashMap<>(); formParams.put("key","test"); formParams.put("file",file); formParams.put("token","WXyUseb-D4sCum-EvTIDYL-mEehwDtrSBg-Zca7t:qgOcR2gUoKmxt-VnsNb657Oatzo=:eyJzY29wZSI6InpoYW56aGkiLCJkZWFkbGluZSI6MTY2NTMwNzUxNH0="); Response?response=HttpUtil.upload("https://upload.qiniup.com/",formParams); System.out.println(response);

如何快速封裝外部接口

以實(shí)體項(xiàng)目為例，封裝 ebay接口

public?class?EbayClient?extends?ApiJsonClient?{/***?店鋪配置**?@param?storeId*/public?EbayClient(Long?storeId)?{//TODO?獲取店鋪相關(guān)配置Map<String,?String>?config?=?new?HashMap<>();basePath?=?"https://api.ebay.com";defaultHeaderMap.put("Authorization",?"Bearer?"?+?config.get("accessToken"));defaultHeaderMap.put("X-EBAY-C-MARKETPLACE-ID",?config.get("marketplaceId"));} }

EbayClient 封裝ebay api請(qǐng)求 基礎(chǔ)類

/***?ebay?庫(kù)存相關(guān)api*?@author?andanyang*/ public?class?EbayInventoryClient?extends?EbayClient?{/***?店鋪配置**?@param?storeId*/public?EbayInventoryClient(Long?storeId)?{super(storeId);}/***?庫(kù)存列表**?@param?limit*?@param?offset*?@return*?@throws?IOException*/public?JSONObject?inventoryItem(Integer?limit,?Integer?offset)?throws?IOException?{Map<String,?Object>?queryMap?=?new?HashMap(2);queryMap.put("limit",?limit);queryMap.put("offset",?offset);return?get("/sell/inventory/v1/inventory_item",?queryMap);} }

EbayInventoryClient 封裝ebay 庫(kù)存 api請(qǐng)求

使用

EbayInventoryClient?ebayInventoryClient=new?EbayInventoryClient(1L); JSONObject?jsonObject=ebayInventoryClient.inventoryItem(0,10);/***?訂單相關(guān)api*?@author?andanyang*/ public?class?EbayOrderClient?extends?EbayClient?{/***?店鋪配置**?@param?storeId*/public?EbayOrderClient(Long?storeId)?{super(storeId);}/***?訂單列表**?@param?beginTime*?@param?endTime*?@param?limit*?@param?offset*?@return*/public?JSONObject?orders(String?beginTime,?String?endTime,?int?limit,?int?offset)?{final?String?path?=?"/sell/fulfillment/v1/order";String?filter?=?MessageFormat.format("lastmodifieddate:[{0}..{1}]",?beginTime,?endTime);//Map<String,?Object>?queryMap?=?new?HashMap<>(8);queryMap.put("filter",?filter);queryMap.put("limit",?limit);queryMap.put("offset",?offset);return?get("/sell/inventory/v1/inventory_item",?queryMap);} }

庫(kù)存相關(guān)的使用EbayInventoryClient，訂單相關(guān)的使用EbayOrderClient，是不是很清晰
